it might help at this stage to confuse the issue more and explain how it is planned to get daily total counts:
these bat species do a weird thing called "light sampling" where they go in and out multiple times until the conditons are right and finally leave to forage for the night. Obv, this causes a total screw up if you just simply count the total number exiting - you end up with an order of magnitude more bats than actually exist in the roost. To eliminate this as best as possible we need to total the ins and outs until a peak number is arrived at as follows:
If we set A or "out" = plus one and B or "in" = minus one
thus:
Code:
dinrection total
out +1 1
out +1 2
out +1 3
out +1 4
in -1 3
in -1 2
out +1 3
etc. this way at some point in each evening there is a maximum in the total column which will more or less equate to the total number in the roost

Hi Corona, not research, monitoring the poplulations since they are protected species.
Greater and Lesser horseshoe bats.

HI there,
I'm trying to find a way of showing the IO's performed by individual programs. Number of reads/writes IO time that kind of thing.
Anybody know of any way to show this information. Free little downloads that kind of thing?

histo
HISTO(1) General Commands Manual HISTO(1)NAME
histo - compute 1-dimensional histogram of N data columns
SYNOPSIS
histo [-c][-p] xmin xmax nbins
histo [-c][-p] imin imax
DESCRIPTION
Histo bins columnular data on the standard input between the given minimum and maximum values. If three command line arguments are given,
the third is taken as the number of data bins between the first two real numbers. If only two arguments are given, they are both assumed
to be integers, and the number of data bins will be equal to their difference plus one. The bins are always of equal size.
The output is N+1 columns of data (for N columns input), where the first column is the centroid of each division, and each row corresponds
to the frequencies for each column around that value.
If the -c option is present, then histo computes the cumulative histogram for each column instead of the straight frequencies. The upper
value of each bin is printed also instead of the centroid. This may be useful in computing percentiles, for example. Values below the
minimum specified are still counted in the cumulative total.
The -p option tells histo to report the percentage of the total number of input lines rather than the absolute counts. In the case of a
cumulative total, this yields the percentile values directly. Values above the maximum are counted as well as values below in this case.
All input data is interpreted as real values, and columns must be white-space separated. If any value is less than the minimum or greater
than the maximum, it will be ignored unless the -c option is specified.
EXAMPLE
To count data values between -1 and 1 in 50 bins:
histo -1 1 50 < input.dat
To count frequencies of integers between 0 and 255:
histo 0 255 < input.dat
